In SQL the statement select*from R,S is equivalent to:_______(a) Select * from R natural join S(b) Select * from R cross join S(c) Select * from R union join S(d) Select * from R inner join S
Answer: (b) Select * from R cross join S
Explanation: The SQL query command, Select * from R, S selects each rows from table R and merges combines it with each row of table S such that the number of columns increases. The merging could be said to be horizontal in nature since it results in an increased number of data columns. The Cross join method produces the same exact result with the output all columns in both tables (R and S). The inner join combines rows in tables as well but requires that both tables have a matching column values. The union join merges data the data in both tables vertically and will not produce the same output as the SELECT * FROM R, S statement.

Select the invalid declaration from the lines of Java code below
int zebraCnt = 40000;
long birdCnt = 222_222_222_222_222L;
a. float avg = 23.5;
b. double avg = 98.32121;
c. None of the above. d. All are legal declaration.
Answer:
float avg = 23.5;
Explanation:
Given
The declarative statements
Required
Determine which of them is invalid
Analyzing them one after the other;
int zebraCnt = 40000;
This statement is valid as zebraCnt is correctly declared as type integer
long birdCnt = 222_222_222_222_222L;
This statement is valid as birdCnt is correctly declared as type long
float avg = 23.5;
This statement is invalid as avg is incorrectly declared as type float.
To correctly declare avg, you either change the datatype to double: as follows;
double avg = 23.5;
or append f to the declaration; as follows
float avg = 23.5f;
double avg = 98.32121;
This statement is valid as avg is correctly declared as type double
Hence, the incorrect declarative statement is float avg = 23.5;
Draw a flowchart or write pseudocode to represent the logic of a program that allows the user to enter a value for one edge of a cube. The program calculates the surface area of one side of the cube, the surface area of the cube, and its volume. The program outputs all the results.
Answer:
I'll answer this question with a Pseudocode
1. Start
2. Input Length
3. Surface Area1 = Length * Length
4. Surface Area2 = 6 * Surface Area1
5. Volume = Length * Length * Length
6. Print Surface Area1
7. Print Surface Area2
8. Print Volume
9. Stop
Explanation:
The first line starts the Pseudocode
The second line accepts input for Length of the cube
The third line calculates the surface area of 1 side
The fourth line calculates the surface area of the cube
The fifth line calculates the volume of the cube
The sixth to ninth line prints the calculated parameters
The Pseudocode ends on line 9

Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way seems to be "quick and easy"? What value is provided by using an "engineering" approach? Also, Give a specific example of an organization (not one listed in the book) that does a good job of this and why.
Answer:
It encourages the documentation of the building process and serves as a good reference point when information about the system is needed. It also helps in the testing of the various components of the system for efficiency.
Explanation:
System analysis is the total evaluation of the working components of a system. it shows the health or functionality of components and analyzes the effect of their relationship on the total system performance.
The design methodology is an engineering process to achieving a complete system build. It follows a procedure, documenting its parameters and observations as the system is implemented.
Example of organizations that follows these methods in building their systems are automobile industries like Honda.
It promotes the recording of the construction process and acts as a helpful resource when details about the system are required. Additionally, it aids in the efficiency testing of the system's many parts.
What is System Analysis?"The process of evaluating a procedure or business to define its aim and purposes and build systems and procedures that will efficiently achieve them," according to the definition of systems analysis.
System analysis is done to investigate a system or its components in order to pinpoint its goals. It is a technique for solving problems that makes the system better and makes sure that all of its parts function effectively to serve their intended purposes.
Six essential steps can be taken while creating a system. Systems analysis entails specifying the problem, its causes, the proposed solution, and the information need that a system solution must satisfy.
System analysis has a wide range of advantages, but it may also have significant drawbacks. The danger of conducting excessive analysis, which may be expensive and time-consuming, is one of the key drawbacks that is frequently disregarded. Finding the ideal balance is consequently a necessary aspect of the analyst's job.

the word biodegradable on a label doesn't necessarily mean a product is environmentally safe?
Answer:
Biodegradable means it SHOULD be safe for the environment. Meaning it can break down into natural elements. However, this is uncertain as some materials don't break down as easily, with a possibility of not having much of a difference as non-biodegradable materials. It all depends on the product, but if we're going by the label, then by definition it's environmentally safe.

An Agile Team decides they want to use pair programming in future Iterations. Where should this be captured? g
Answer:
The decision to use pair programming by an Agile Team should be captured in their Inspect and Adapt meeting notes.
Explanation: The underlying principle for having an agile team that the team is committed to constant incremental and or progressive improvement.
Inspect and Adapt Meeting Notes are notes which hold the summary of past achievements which hold and records of things to do going forward in order to ensure that there is progress and improvement over the last set of objectives.
These notes are usually taken at the Inspect and Adapt meeting. This is simply a meeting held at the end of each project milestone. An agile team during this meeting will review its performance, agree and document how it can be more effective.
Pair programming is also an Agile practice in the parlance of software development. Instead of the regular method where an individual is tasked with the development of an application, in this case, two programmers are tasked with the development of one App.
Sometimes this method is used during Extreme Programming (XP)
